In the past few years, the research effort on 2D materials has rapidly increased, driven by the great variety of layered materials and their exceptional properties when reduced to a few atomic layers ...

Researchers at Tohoku University in Japan claim to have developed a tin(II) sulfide (SnS) solar cell with a high open-circuit voltage, due to an SnS interface exhibiting large band bending. The novel ...

Scientists at Germany's Fraunhofer Institute for Solar Energy Systems ISE have demonstrated a triple-junction solar cell with a perovskite-perovskite-silicon subcell configuration. They said the cell ...

The open-circuit voltages of mature single-junction photovoltaic devices are lower than the bandgap energy of the absorber, typically by a gap of 400 mV. For CdTe, which has a bandgap of 1.5 eV, the ...
